ELECTRIC FLATIRON.

Specification of Letters Patent.

Patented J an. 6, 1920.

Application filed March 5, 1919. Serial No. 280,794.

To all whom it may concern:

Be it known that I, -WILLIAM MORGAN, a citizen or the Jnited States, residing at 722 So. Broadway, Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Electric Flatirons, of which the following is a specification.

My invention relates to electric fiat irons and the like, and consists of the novel features herein shown, described and claimed.

One of the principal objects of this invention is to make a timer so that when the electricity has been turned on to heat the flat iron the timer may be set to turn off the electricity after the iron has been heated a predetermined length of time.

Figure 1 is a perspective of an electric flat iron embodying the principles of my in vention.

Fig. 2 is a vertical longitudinal fragmentary sectional detail showing the circuit breaker and the timing device.

Fig. 3 is a vertical cross sectional detail on the line 3-3 of Fig. 2.

Fig. 4 is a vertical cross sectional detail The flat iron 1 may be provided with an electric heating element of any desired construction. A plug socket 2 extends up wardly from the top of the rear end of the flat iron 1, and the terminals 3 and 4 lead to the contact heads 5 and 6. The socket 2 has a lining 7 of insulation, and the terminals 3 and 4 lead through the lining to the contact heads 5 and 6. The insulating plug 8 is mounted to slide up and down in the socket 2 and'the terminals 9 and 10 of the electric supply line pass into the upper e d of the plug and connect electrically with screws 11 and 12. The body 13 of the plug is insulation. Spring casings 14 and 15 are formed by boring from the lower end of the plug, and the screws 11 and 12 are at the bottoms of the spring casings and screwed into the insulation, electric Wires being bent around the heads of the screws. Springs 16 and 17 are placed in the spring casings 14 and 15 against the screw heads. Spring seats 18 and 19 fit in the spring casings against the springs. The yielding contacts 20 and 21 extend from the spring seats 18 and 19 through plugs 22 and 23 screwed into the ends of the bores forming the spring casings 14 and 15 in position to engage the fixed contacts 5 and 6.

A head 24 is fixed in the upper end of the body 13, and an arm 25 extends upwardly from the head. A supplemental handle 26 is formed of sheet metal and is adapted to closely fit against the lower face of the main handle 27. Ears 28 extend from the post 29, there being an opening through the post between the ears, and an arm 30 extends Tom the supplemental handle 26 through the opening between the ears, and a pivot 31 is inserted through the ears and through the arm. A pivot 32 connects the outer end of the arm 30 to the arm 25. A spring 33 is mounted in a recess 34 formed upwardly in the main handle 27, one end of the spring being connected to the main handle and the other end of the spring being connected to .the supplemental handle 26, and the tension of the spring being exerted to throw the free end of the supplemental handle 26 downwardly to raise the plug 8 to raise the contacts 20 and 21 and break the connection with the contacts 5 and 6 so as to shut oil the electricity from the flat iron, and so that when the supplemental handle 26 is raised upwardly against the bottom of the main handle 27 the plug 8 will be pressed downwardly to make the electrical connections and heat the flat iron.

The post 35 supports the opposite end of the main handle 27 from the post 29. A vertical. straight slot 36 is formed through the post 35, a notch 37 extends laterally from the upper end of the slot 36, and a notch 38 extends laterally from the lower end of the slot 36. A cylindrical cup 39 has a removable cap 40, a stem 41 is slidinly mounted through the cap 40, a head 42 is fixed upon the lower end of the stem 41 and fits closely in the chamber 43 of the cylindrical cup 39, a fiat valve 44 is mounted upon the lower face of the head 42 to cover the port 45 through the head, a small port 46 is formed through the head at the opposite side from the port 45, an expansive coil spring 47 is mounted upon the stem 41 against the cap 40, a stuffing box construction 48 is formed around the stem 41 in the cap 40, a crosshead 49 is screwed upon the stem 41 against the spring 47, a handle 50 extends outwardly from the crosshead 49, and an arm 51 extends from the crosshead 49 through the slot 36. The lower end of the spring 47 is connected to the stuffing box construction 48 and the upper end of the spring is connected to the crosshead 49, the

tension of the spring being exerted to push the arm 51 to the left, when seen as in Fig. 4. The point of the arm 51 is adapted to engage under the point of the supplemental handle 26.

l/Vhen it is desired to start heating the flat iron, the handle is engaged to move the head 42 upwardly in the cup and to move the arm 51 upwardly in the slot 36 and turn the arm into the notch 37; then the supplemental handle 26 is swung upwardly and the handle 50 released and the arm 51 will swing under the tip of the handle 26.

It is to be understood that the cup 39 is filled with oil 52, and when the head 42 goes up in the cup the valve 14 will open and the oil on top of the head. 42 will pass through the port 34 to the bottom of the head; then the valve 14 will close with the oil below the bottom of the head 42. The tension of the spring 33 pressing downwardly upon the arm 51 will overcome the tension of the spring 17 and press the head 42 downwardly against the oil, and the oil will flow through the small port 46 and thehead 42 will descend until the arm 51 reaches the notch 38; then the spring 47 will swing the arm 51 into the notch 38 out from under the tip of the supplemental handle 26 and release the handle as the tension of the spring 33 will swing the handle downwardly to raise the plug 8 and break the electrical connection and stop heating the iron.

The quantity of oil 52 in the cup, the size of the port 46, the tension of the spring 33, and the length of the slot 36 will all combine to determine the time during which the electricity will circulate through the heating element to heat the iron and this time may be varied greatly and to suit.

The supplemental handle 26 controls the circuit breaker, and this supplemental handle is controlled by the timing mechanism. The timing mechanism is the dash pot. When the flat iron is in use in ironing the supplemental handle 26 may be held up by the hand of the operator to heat the iron and when the iron is hot enough the supplemental handle may be released until more heat is desired.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim:

1. The combination with an electric flat iron having a plug socket extending upwardly fn m the top or" its rear end and the terminals of its heating element leading into the socket; of a plug slidingly mounted in the socket and having spring pressed terminals to engage the first terminals; a supplemental handle mounted below the main handle and connected to the plug, so that when the supplemental handle is raised the electricity is turned on, and so that when the supplemental handle is lowered to the limit the electricity is turned off; and timing mechanism for holding the supplemental handle raised to heat the iron for a predetermined time and then release the supplemental handle to stop the heating operation.

2. The combination with an electric flat iron having a plug socket extending upwardly from the top of its rear end and the terminals of its heating element leading into the socket, and a main handle mounted on posts above the body of the flat iron; of a plug slidingly mounted in the socket and having spring pressed terminals adapted to contact with the first terminals; a supplemental handle pivotally mounted below the main handle and connected to the plug; a spring for pressing the supplemental handle downwardly to break the electric connection; and a dash pot for holding the supplemental handle upwardly to make the connection for a predetermined time.

In testimony whereof I have signed my name to this specification.

WILLIAM MORGAN.
